The label from "GeoCentral, Discover The Wonders Of Our World" reads, "Break-Your-Own Geodes!" and adds "90% of these geodes have hollow centers with crystals. Take a chance! You might be lucky.

Geodes are formed from fluids wich crystallize in cavities within the rounded rock or nodule. They are found in many parts of the world. These geodes come from Mexico.

HOW TO BREAK OPEN YOUR OWN GEODEPut the geode in a bag or a sock. Hit it firmly wth a hammer aiming for the center.* Take care not to hit your fngers. Be sure to use an old sock -- it will probably get a hole in it!* Adult supervision suggested for children under 10".

I would suggest it is more fun to whack the sock onto a steel plate on the floor than hit it with a hammer.

The best way to break geodes is to tape two triangle files to the faces of a large vise. Put the geode betwen the points of the files and close the vise. The geode will crack on a line between the two file points. Wear safety glasses; expect the two halves to fly.

Quartz

Azurite after Malachite, Chalcocite after Malachite, Cuprite, Prehnite, and a couple I have not been able to identify (but also after malachite) -- and copper is still possible, but more likely has become a pseudomorph.

From the collection of John Betts, #27592. From the collection of A. Lincoln Sherk, MD. (1890s-1969). From the collection of M. Biernbaum Baldwin.
The original label was included and lists "Coll. of M. G. Biernbaum". Biernbaum changed his name to Baldwin.

IMRMC Christmas Gift arranged by Ed Benjamin; from the collection of Kurt Patzlaff (www.amber-werx.com). This is young amber that is only about a million years old. Tree bark cast mold, but no insects.

From the collection of John Betts, #29196. From the collection of A. Lincoln Sherk, MD. (1890s-1969). From the collection of Reuben Haines, #D746; label notes #28.3.1.1 (which I assume is Dana). From the collection of D. Conrad (not sure of first initial on label); Conrad was probably between Sherk and Haines.
Reuben, a noted early Quaker mineral collector and a founding member of the Academy of Natural Sciences in Pennsylvania, lived in Germantown. The specimen was probably collected in the late 1700s or early 1800s.
The three parts of this specimen (1771, 1772, 1773) fit together to make a 'lenticular crystal of gypsum' as noted on Conrad's label.

From the collection of Rob Lavinski, #T100. From the Carl Bosch collection at the U.S. National Museum, Divison of Mineralogy, #B12350. From the collection of Staatl. Mineralien-Niederlage, #14198. From the collection of Sanco Global Resources. From The John F. Barlow Mineral Collection, #1728. Specimen was "Restored" per label on specimen that appears identical to the Barlow # near it.

With the agrellite is red eudialyte, black amphibole, white feldspar, and a little greenish mosandrite. Under SW you'll also see a lot of brilliant green fluorescing due to a thin film of what is most likely opal/hyalite.

From the collection of Tim Jokela, Jr. This is a Type Locality specimen for Agrellite.

From the collection of John Betts, #29651. The label indicates this is a Type Locality specimen; I have checked several reputable sources and now have four type localities (they all appear to be near each other).

From the collection of Keith Hayes. From the collection of IMRMC.
Scapolite is a synonym for the Marialite-Meionite Series, and is usually considered to be a mix of Marialite, Wernerite, and Meiolite. The label notes it glows under SW.

Collected by Kitty & Bill Heacox; received as a gift. Expected shipping damage on something this fragile produced two fine minatures (#1865, 1866), a great thumbnail (#1854), and many excellent micros (traded/gifted, not cataloged).

From the collection of IMRMC. From the collection of Keith Hayes. From the collection of Alessandro Genazzani. Under 'Alessandro Genazzani' the label notes 'Via G. Jervis, 3, Tel. (055) 453.900, C.A.P. 50141 (FIRENZE)'. Some of the Hematite exhibits iridescence.

From the collection of John Betts, #30423. From the collection of Jay Lininger (1939-2004) Pennsylvania Mineral Collection, #PM-045; auction lot 253, item no. 01229. From the collection of Bryon Brookmyer, who collected it. Betts label notes Lininger # as P-045, and date collected as 1974. Back of Lininger label notes: 1 3/4 x 2 3/4"; front notes "Superb crystallized specimen". The selenium crystals formed
when a coal culm bank burned, causing the selenium to precipitate. It was reported as having been started by lightning, so this is a native element.

From a trade with Kenny Gay, who collected it. This is an extremely fine grained dike diabase from near the upper surface. The diabase is Juriassic in age; the dike at the quarry is still a concordant sill; the Triassic sediments that overlay the diabase are baked to a black shale like rock.

From the collection of Daniel & Carolyn Zabriskie (Many Facets), #SMP-01314-URALIT. Uralite is a hornblende group mineral, usually actinolite, pseudomorph after a pyroxine group mineral, usually augite. This specimen appears to be actinolite pseudomorph after jadeite.

From the collection of Daniel & Carolyn Zabriskie (Many Facets), #SMP-01699; label notes 'Good Cutting Material" and places Tres Hermanes in CA. From the collection of Daniel & Carolyn Zabriskie (Many Facets), #ADPT05XX_129; this older label gives correct location, and the numbering supports it came to Dan from Melvyn Machin as part of a bulk lot.
